Chaihu Guizhi Ganjiangtang （CGG）is a classic prescription in the Treatise on Cold Damage，which has the effects of clearing and relieving stagnation heat in Shaoyang，warming and dissolving water drink，and relieving the pivot mechanism. It is a classic prescription for treating spleen deficiency and liver depression and stopping internal stagnation caused by water drink. The formula is exquisite and well-matched and is often modified and used by ancient and modern medical practitioners to treat various miscellaneous diseases of internal and external medicine，with significant therapeutic effects. In recent years，with the rapid development of modern pharmacology，research on the micro mechanism of CGG has been continuously developed and deepened，providing new ideas for the treatment of diseases with CGG. Therefore，the authors systematically searched databases such as China National Knowledge Infrastructure，Wanfang Data Knowledge Service Platform，VIP Database， and PubMed for literature on the clinical application and pharmacological mechanism of CGG published by Chinese and foreign scholars in recent years. This article summarized the literature from two aspects：the modern clinical application and mechanism of action of CGG and elaborated on the diseases treated by CGG in modern literature，involving digestive system，respiratory system，nervous system，endocrine system，circulatory system，urinary system，gynecology，as well as its application in reducing the side effects of radiotherapy and chemotherapy， gynecology， dermatology， ophthalmology， and orthopedics. At the same time，the mechanism of CGG in treating diseases may be related to anti-inflammatory，anti-oxidative stress， regulation of immunity， anti-fibrosis， anti-tumor， improvement of gastrointestinal flora and motility， protection of liver tissue， reduction of blood lipids and blood sugar， and regulation of hormone levels.

BACKGROUND:Carnosic acid,a bioactive compound found in rosemary,has been shown to reduce inflammation and reactive oxygen species(ROS).However,its mechanism of action in osteoclast differentiation remains unclear. OBJECTIVE:To investigate the effects of carnosic acid on osteoclast activation,ROS production,and mitochondrial function. METHODS:Primary bone marrow-derived macrophages from mice were extracted and cultured in vitro.Different concentrations of carnosic acid(0,10,15,20,25 and 30 μmol/L)were tested for their effects on bone marrow-derived macrophage proliferation and toxicity using the cell counting kit-8 cell viability assay to determine a safe concentration.Bone marrow-derived macrophages were cultured in graded concentrations and induced by receptor activator of nuclear factor-κB ligand for osteoclast differentiation for 5-7 days.The effects of carnosic acid on osteoclast differentiation and function were then observed through tartrate-resistant acid phosphatase staining,F-actin staining,H2DCFDA probe and mitochondrial ROS,and Mito-Tracker fluorescence detection.Western blot and RT-PCR assays were subsequently conducted to examine the effects of carnosic acid on the upstream and downstream proteins of the receptor activator of nuclear factor-κB ligand-induced MAPK signaling pathway. RESULTS AND CONCLUSION:Tartrate-resistant acid phosphatase staining and F-actin staining showed that carnosic acid dose-dependently inhibited in vitro osteoclast differentiation and actin ring formation in the cell cytoskeleton,with the highest inhibitory effect observed in the high concentration group(30 μmol/L).Carnosic acid exhibited the most significant inhibitory effect during the early stages(days 1-3)of osteoclast differentiation compared to other intervention periods.Fluorescence imaging using the H2DCFDA probe,mitochondrial ROS,and Mito-Tracker demonstrated that carnosic acid inhibited cellular and mitochondrial ROS production while reducing mitochondrial membrane potential,thereby influencing mitochondrial function.The results of western blot and RT-PCR revealed that carnosic acid could suppress the expression of NFATc1,CTSK,MMP9,and C-fos proteins associated with osteoclast differentiation,and downregulate the expression of NFATc1,Atp6vod2,ACP5,CTSK,and C-fos genes related to osteoclast differentiation.Furthermore,carnosic acid enhanced the expression of antioxidant enzyme proteins and reduced the generation of ROS during the process of osteoclast differentiation.Overall,carnosic acid exerts its inhibitory effects on osteoclast differentiation by inhibiting the phosphorylation modification of the P38/ERK/JNK protein and activating the MAPK signaling pathway in bone marrow-derived macrophages.

Objective:It analyzed the population aggregation characteristics of the treatment costs for Traditional Chinese Medi-cine(TCM)dominant diseases,and make targeted recommendations for relevant health policies.Methods:A total of 205 medical insti-tutions were obtained through stratified whole-cluster sampling to analyze the composition of the beneficiary population based on Sys-tem of Health Accounts 2011 for the treatment costs of TCM dominant diseases for local residents in Beijing in 2019.Results:The treatment costs of Beijing's TCM dominant diseases are dominated by diseases that include basic western medicine treatment,with male patients'costs accounting for a higher proportion than those of females,and the trend of younger patients in types of diseases treated by TCM and the costs have mainly flowed to females,with more than 50%of the treatment costs being consumed by patients aged 60 years old and above.Conclusion:It is needed to pay attention to male and child patients aged 0～14 years and their priority diseases,strengthen the construction of Chinese medicine geriatric health services,and adopt differentiated strategies for different groups of people so as to maximize the advantages of Chinese medicine.

Objective To optimize the operational steps and processes in mouse cervical heterotopic heart transplantation by modifying the conventional cuff technique for vascular anastomosis and consequently establish a more stable cervical heterotopic heart transplantation model in mice.Methods C57BL/6 male mice (6～8 weeks old,weighing 20～24 g)were categorized into control (conventional cuff technique)and experimental groups (our"Anchoring Node"technique).Time for each surgical step,frequencies of vascular everting and vascular trimming,and the reasons for failure were recorded and compared between the 2 groups. Postoperative survival of heart allograft was determined by daily observation and touching,and the mice with the survival time>48 h were considered as successful model establishment.On the 7th and 14th days after surgery,HE staining was used to observe the pathologic changes in the vascular tissues at anastomosis.The expression of troponin T (cTnT)in the heart on the 7th day was detected with immunofluorescence assay. Results ① In the 25 hearts from each group,2 hearts from the experimental group and 8 from the control group failed,and the survival rate of heart allografts was 92％and 68％,respectively.In the experimental group,arterial and venous everting occurred at an average of 1 .16 times,with an average frequency of trimming of 0.04 times,while in the control group,arterial and venous everting was 2.00 and 2.28 times,respectively,with an average frequency of trimming of 0.21 and 0.46 times,respectively.② Significant differences were observed in the overall duration for cervical heterotopic heart transplantation (77.22±3.82 vs 87.49±8.01 min),vascular separation plus cannulation (30.06±2.68 vs 36.50±6.67 min),and cervical anastomosis (7.31±1 .08 vs 12.34±2.58 min)between the experimental and control groups (all P<0.05).③HE staining displayed that vascular patency was observed in the experimental group on the 7th and 14th days after surgery.④cTnT staining indicated no massive myocardial necrosis was seen in both groups. Conclusion Based on conventional cuff technique for mouse cervical heterotopic heart transplantation,our modified"Anchoring Node"technique ensures the stability and efficiency of one-man microscopic operation with controllable quality,with the advantages of longer postoperative survival of heart allograft,high patency rate of anastomotic vessels,good cardiac function,and fewer postoperative complications.

Objective:To investigate the current status of psychosomatic medical service competence and training needs among general practice resident physicians.Methods:An online questionnaire survey was conducted from August to September 2021, among general practice resident physicians selected by cluster sampling from 4 affiliated hospitals of Tongji University. The questionnaire contained the basic information, the self-assessment and training needs of psychosomatic medical service competence of participants, and psychosomatic medical service requirements of patients in the community.Results:A total of 159 questionnaires were distributed, and 140 were collected (88.1%). The survey showed that 25.7% (36/140) of participants believed that 50% or more patients had physical symptoms accompanied by emotional problems; 29.3% (41/140) thought that 50% or more patients had sleep problems, but 60.0% (84/140) of them failed to provide appropriate treatment. The rate of "core knowledge and concepts of psychosomatic medicine" was 47.5% (665/1 400) and the correct rate of "common psychosomatic diseases" was (64.6±23.4)%. Merely 21.4% (30/140) participants reported satisfaction with the psychosomatic medical service competence; 62.8% (88/140) respondents believed that the coverage rate of the above-mentioned competence training in the current general practice residential training program was less than 50%, and 66.4% (93/140) supported that more psychosomatic training was "necessary". The acceptance rate of online training, workshops, MDT, and clinical practice ranged from 56.4% (79/140) to 63.4% (89/140).Conclusions:The survey indicates that there are large needs for psychosomatic medical services among patients in community, but the competence and confidence of general practice resident physicians to provide the service are significantly insufficient. Therefore, it is suggested to strengthen the training of psychosomatic medical service competence in the general practice residency training program.

【Objective】 To form the sampling data interval by retrospectively analyzing the sampling data of quality monitoring of fresh frozen plasma, cryoprecipitates and leukocyte-free platelets in all blood stations in Hebei Province during the past 7 years. 【Methods】 The data of blood component sampling from 12 blood station quality control laboratories in Hebei from 2015 to 2021 were collected. The FⅧ content and plasma protein content of fresh frozen plasma, the FⅧ content and fibrinogen content of cryoprecipitates, and the leukocyte residuals, red blood cell mixed and platelet content of leukocyte-free platelets were taken as the objects for discrete point and fitted curve analysis. 【Results】 The FⅧ level of fresh frozen plasma: (1.36±1.1) IU/mL, 5 blood stations showed a representative overall high or low or fluctuated characteristics; Fresh frozen plasm-plasma protein items: overall mean ±SD: (61.13±16.7) g/L, four blood stations showed scattered distribution or continuous high value scattered points; Cryoprecipitates FⅧ: the overall mean ±SD: (134.25±58.7) IU/mL, four blood stations showed the differentiation characteristics of continuous high, low or stable in the middle; Cryoprecipitates-fibrinogen items: the overall mean ±SD: (215.27±83.5) mg, five blood stations showed the overall high or low and fluctuated. Leukocyte-free apheresis platelet-to-leukocyte residual items: overall mean ±SD: 0.37±0.96 (×10⁶/bag), two blood stations showed a relatively high representative overall characteristics, and the rest were concentrated between 0 and 1; The total mean ±SD of platelet-to-red blood cell mixture without leukocyte was 2.45±2.82 (×10⁹/bag), with obvious segmented concentrated distribution, and scattered distribution in 3 blood centers. Platelet content: the overall mean ±SD was 3.14±1.55 (×10¹¹/bag), many deviations were noticed in 3 blood stations, and 1 blood station showed representative overall high characteristics. 【Conclusion】 This analysis shows that the distribution status of each blood station in different items is similar. The distribution status of discrete point groups and the change trend of the concentrated part of the fitting curve show that there are some differences in the monitoring level between the quality control laboratories of each blood station, and the update of detection instruments and reagents and the selection of detection methods greatly affect the test results. The summary data presented the index interval framework formed in the past 7 years, which helped to understand the difference between the results of each laboratory, correct the accuracy of the test results, better play the guiding role of quality monitoring in the blood preparation process, and continue to enhance the standardization of the whole process of blood collection and supply in the province.

Objective:Human leukocyte antigen(HLA)B27 is a susceptibility allele of ankylosing spondylitis(AS),and HLA-B27 antigen typing is an important indicator for clinical diagnosis of AS,but current typing methods such as sequence specific primer polymerase chain reaction(PCR-SSP)still possess limitation.Therefore,this study aims to analyze the correlation between B27 subtypes and susceptibility to AS in Hunan Province by applying high-resolution polymerase chain reaction-sequence-based typing(PCR-SBT). Methods:Peripheral blood of 116 patients with suspected AS(suspected AS group)and 121 healthy volunteers(control group)admitted to the Second Xiangya Hospital from January 2020 to December 2020 were collected for HLA-B genotyping by PCR-SBT.Among the patients in the suspected AS group,23 patients were finally diagnosed with AS(confirmed AS group),and the remaining 93 undiagnosed patients served as the non-confirmed AS group.PCR-SBT and PCR-SSP were used to detect HLA-B27 typing in 116 patients with suspected AS,and the results of the 2 methods were compared. Results:The HLA-B27 allele frequency in the suspected AS group was significantly higher than that in the control group[11.63%vs 2.48%;P<0.001,odds ratio(OR)=5.18,95%confidence interval(CI)2.097 to 12.795].B*27:04,B*27:05,B*27:06,and B*27:07 were detected in the suspected AS group and the control group.The frequency of the B*27:04 allele in the suspected AS group was significantly higher than that in the control group(9.48%vs 1.24%;P<0.001,OR=8.346,95%CI 2.463 to 28.282).The positive rate of B27 in the suspected AS group and the confirmed AS group(B27+/+ and B27+/-)was significantly higher than that in the control group(χ2=16.579,P<0.001;χ2=94.582,P<0.001,respectively).Among the confirmed AS group,21 were HLA-B27 carriers,and the B27 positive rate in the confirmed AS group was 91.3%.PCR-SBT could achieve high resolution typing of the HLA-B gene locus,with higher sensitivity,specificity,positive predictive value,negative predictive value,and accuracy than PCR-SSP. Conclusion:PCR-SBT typing analysis shows a strong correlation between HLA-B * 27:04 and AS in Hunan province.The PCR-SBT method can be used as the preferred option for the auxiliary diagnosis of clinical AS.

Objective:To investigate the treatment strategy for pediatric humeral supracondylar fractures with callus formation and displacement neglected for over 1 week.Methods:A retrospective analysis was made of the clinical data of 36 children who had been treated at Department of Pediatric Orthopaedics, Medical Center, The Second Affiliated Hospital, Inner Mongolia Medical University from January 2011 to January 2021 for humeral supracondylar fractures with callus formation and displacement neglected for over 1 week. There were 22 boys and 14 girls, with an age of (6.7±2.7) years (from 2.3 to 12.8 years). All fractures were Gartland type Ⅲ. The patients were divided into 2 groups according to their treatment methods: a closed reduction and percutaneous pinning (CRPP) group of 15 patients subjected to the CRPP treatment only, and a leverage group of 21 patients subjected to CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling. The 2 groups were compared in terms of operation time, fluoroscopy frequency, quality of reduction, and recovery time for elbow range of motion; the elbow range of motion, visual analogue scale (VAS), Mayo elbow performance score (MEPS) and complications were assessed at the last follow-up.Results:The 2 groups were comparable because there was no significant difference between them in the general information before operation ( P>0.05). All patients were followed up for (26.2±16.3) months (from 6 to 96 months). All the fractures obtained acceptable reduction and clinical union 4 to 6 weeks after operation. The operation time [(28.2±6.8) min] and fluoroscopy frequency [(27.0±6.0) times] in the leverage group were significantly less than those in the CRPP group [(40.8±10.8) min and (43.3±11.4) times] ( P<0.05). The CRPP group was significantly better than the leverage group in the intraoperative Baumann angle (78.1°±1.6° versus 73.7°±4.1°), lateral capitellohumeral angle (58.3°±2.6° versus 49.6°±5.2°) and horizontal rotation rate (109.5%±3.0% versus 103.2%±4.9%) ( P<0.05). The intraoperative reduction in the CRPP group was significantly closer to the normal mean value than that in the leverage group ( P<0.05). There was no significant difference in the recovery time for elbow range of motion between the CRPP and the leverage groups ( P>0.05). At the last follow-up, the Baumann angle (75.4°±2.8°) and the lateral capitellohumeral angle (53.2°±3.6°) in the leverage group were still significantly better than those in the CRPP group (78.3°±1.5° and 57.5°±2.3°) ( P<0.05). However, there was no significant difference in the elbow range of motion, VAS, MEPS or incidence of complications between the 2 groups ( P>0.05). Conclusion:To treat humeral supracondylar fractures with callus formation and displacement neglected for over 1 week in children, CRPP assisted by the "lever technique" with posterior elbow Kirschner wire prying and pulling is an efficient and accurate method, because it can lead to more satisfactory reduction than CRPP only.

Objective:To investigate the effect of ubiquitin binding enzyme 2T (UBE2T) on the radiosensitivity of lung adenocarcinoma and unravel its possible mechanism.Methods:A total of 45 patients pathologically diagnosed with different stages of lung adenocarcinoma and treated with radiotherapy in the Second Affiliated Hospital of Zunyi Medical University from March, 2019 to December, 2021 were enrolled, and the efficacy was evaluated according to response evaluation criteria in solid tumors (RECIST1.1). All patients were divided into radiosensitive group ( n=25) and radioresistant group ( n=20). Radiosensitive group was complete remission (CR)+partial remission (PR), and radioresistant group was stable disease (SD) + progression disease (PD). Immunohistochemistry (IHC) was used to calculate the score based on the staining intensity and the number of positive cells. Chi-square test was combined to analyze the correlation between the expression level of UBE2T in paraffin specimens of lung adenocarcinoma patients and the radiosensitivity of patients. Lentivirus UBE2T-interfered (UBE2Tsh) A549 and UBE2T-overexpressed SPC-A-1 lung adenocarcinoma cells and their respective controls were constructed for irradiation and colony formation assay. The survivor fraction curve was fitted by single-hit multi-target model. The DNA double-strand break (DSB) marker γH2AX foci were detected by immunofluorescence (IF). The expression levels of UBE2T, γH 2AX and Rad51 proteins were detected by Western blot. Cell cycle and apoptosis rate of A549 were determined by flow cytometry. Binary variables were statistically analyzed by Fisher's exact probability method and measurement data were assessed by t-test. Results:High-expression level of UBE2T was correlated with the radiosensitivity of lung adenocarcinoma patients ( P<0.05). UBE2Tsh improved the radiosensitivity of A549 lung adenocarcinoma cells, and the sensitizing enhancement ratio (SER) was 1.795. UBE2T overexpression decreased the radiosensitivity of SPC-A-1 lung adenocarcinoma cells with an SER of 0.293. γH2AX foci number per cell were significantly increased in UBE2Tsh A549 cells after irradiation ( P<0.01) . Compared with the control group, the expression level of γH2AX protein was up-regulated ( P<0.01)and that of Rad51 protein was down-regulated in UBE2Tsh A549 cells after radiation ( P<0.001). Compared with the control group, the expression level of γH2AX protein was down-regulated ( P<0.05) and that of Rad51 protein was up-regulated in UBE2T overexpressed SPC-A-1 cells ( P<0.001). The proportion of UBE2Tsh A549 cells in G 2 phase was decreased ( P<0.01) and cell apoptosis was increased ( P<0.001). Conclusions:UBE2T might promote the radioresistance of lung adenocarcinoma cells by enhancing DNA DSB repair induced by radiotherapy, inducing cell cycle G 2 phase arrest, and reducing cell apoptosis.

Objective:To evaluate the preoperative localization value of endoscopic ultrasound guided fine needle tattooing (EUS-FNT) for laparoscopic distal pancreatectomy in pancreatic lesions with a maximum diameter ≤3 cm.Methods:From November 2017 to October 2022, at the Second Affiliated Hospital of Soochow University, the data of patients with pancreatic lesions ≤3 cm who underwent laparoscopic distal pancreatectomy were retrospectively analyzed. Eight patients who underwent EUS-FNT assisted laparoscopic distal pancreatectomy were included in the fine needle tattooing (FNT) combined laparoscopic group. And 14 patients who underwent simple laparoscopic distal pancreatectomy were taken as the simple laparoscopic group. The success rate and complications of EUS-FNT were observed. The differences in operation time, surgery-related complications and complete resection rate of lesions between the two groups were compared. Mann-Whitney U test and descriptive analysis were used for statistical analysis. Results:In the FNT combined laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 4 cases in the pancreatic tail. In the simple laparoscopic group, the lesions of 4 cases were located in the pancreatic body and 10 cases in the pancreatic tail. There was a significant difference in lesion size between the two groups (14.5 mm (10.8 mm, 16.5 mm) vs. 27.0 mm (23.5 mm, 30.0 mm), Z=-3.09, P=0.001). In the FNT combined laparoscopic group, EUS-FNT was successfully performed in all 8 patients. The average time of laparoscopy after EUS-FNT was (98.4±8.8) min. The marks were clearly visible under the laparoscopic field of view, and no complications such as abdominal hemorrhage and hematoma were observed. Laparoscopic pancreaticocaudectomy was performed in 5 cases and pancreaticocaudectomy plus splenectomy in 3 cases. The median operation time was 192.5 min (176.3 min, 203.8 min). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. The lesions were one-time completely resected in all 8 patients. The postoperative pathology were 6 cases of pancreatic neuroendocrine neoplasm, 1 case of intraductal papillary mucinous neoplasm (IPMN), and 1 case of solid pseudopapilloma. In the simple laparoscopic group, laparoscopic pancreaticocaudectomy was performed in 2 cases and pancreaticocaudectomy plus splenectomy in 12 cases. The median operation time was 202.5 min (192.8 min, 235.0 min), which was longer than that of FNT combined laparoscopic group, but the difference was not statistically significant ( P>0.05). The amount of intraoperative bleeding was large in 2 patients and blood transfusion was needed. In 1 patient with pancreatic body lesions, no lesion was found in the specimen examination after the first pancreatectomy, and the lesions were completely resected after the second partial pancreatectomy. Active abdominal hemorrhage occurred in 1 patient on the second day after operation, and underwent interventional embolization for hemostasis. Two weeks after surgery, 1 patient was found to have a encapsulated fluid with a long diameter of 6 cm around the pancreas by computed tomography re-examination 2 weeks after surgery. The postoperative pathology were 5 cases of pancreatic neuroendocrine neoplasm, 2 cases of IPMN, 1 case of solid pseudopapilloma, 1 case of pancreatic cyst with glandular low-grade intraepithelial neoplasia, 1 case of ectopic spleen, and 4 cases of pancreatic ductal adenocarcinoma. Conclusion:EUS-FNT can effectively localize small pancreatic lesions before laparoscopic distal pancreatectomy, shorten the operation time and improve the complete resection rate under laparoscopy.
